IT notices: Downtime for infrastructure upgrade 21 & 22 November 2018

There will be two periods of planned downtime impacting the Balancing Mechanism Reporting Service (BMRS) from 17:15 to 22:15 on 21 November 2018 and again from 03:15 to 08:15 on 22 November 2018.

Both periods of planned downtime are required for National Grid and Elexon to carry out the communications line infrastructure upgrade.

How will I be impacted?

During the outage, the National Grid applications which includes Balancing Mechanism (BM) and Market Operation Data Interface System (MODIS), will be suspended and will not be sending data to BMRS.

Therefore all data normally received from National Grid applications will not be updated via the BMRS Website, APIs, Data Push Service and TIBCO.

This includes REMIT and European Transparency Regulation (ETR) data sent from National Grid’s MODIS system and as a result, there will be a delay for BMRS in sending ETR to ENTSO-e Transparency Platform from BMRS.

Furthermore Settlement Calculations will be suspended on the BMRS and be restarted at the end of each period of downtime.

Parties who currently use the Elexon Portal POST API interface (https://www.elexonportal.co.uk/postremit) to submit REMIT files to BMRS will not be impacted by this outage and the data will continue to be published on BMRS as normal.

Following this planned downtime, the BMRS will start processing the backlog and we expect website and APIs will be fully updated by approximately 10:00 (GMT) on 22 November 2018. The remaining BSC Central Systems are unaffected by this planned downtime.

What do I need to do?

You do not need to take any specific action but just note the impact to parties during this planned outage.

Is there anything else I need to know?

No.

However, any BSC Parties having questions for National Grid regarding the impact of this outage on the Electronic Data Transfer (EDT), Electronic Data Logging (EDL) submissions, should phone 0800 917 7111 or 0800 085 4806. Overseas callers should use +44 870 521 6121 and quote “NETA EDT”.
